A conversation with Deep Rising filmmaker Matthieu Rytz about the promise and the peril of mining the ocean floor.

“To say, ‘Don’t harm the ocean’ — it is the easiest message in the world, right? You just have to show a photo of a turtle with a straw in its nose,” Michael Lodge, the secretary general of the U.N.’s International Seabed Authority, told The New York Times last year. “Everybody in Brooklyn can then say, ‘I don’t want to harm the ocean.’ But they sure want their Teslas.”
Canadian filmmaker Matthieu Rytz apparently didn’t get the memo. Deep Rising, his new documentary narrated by Jason Momoa, aims at one of the great contradictions of the energy transition: that deep-sea mining could provide a wealth of copper, nickel, and cobalt, the battery materials that are critically needed for EVs and clean-energy storage — and could also trigger ecological collapse in the fragile Pacific Ocean abyss.
At the center of this debate is the International Seabed Authority, a Jamaica-based U.N. organization tasked with the conflicting goals of protecting the ocean floor and writing regulations for the extraction of “polymetallic nodules.” The metal-rich nodules are sprinkled across an internationally governed part of the Pacific called the Clarion-Clipperton Zone, which starts about 500 miles south of Hawaii and by some measurements stretches roughly twice the size of India. By the estimate of The Metals Company, which has a multi-billion-dollar stake in an eventual mining operation, the supply of nodules would be enough to eventually power “280 million electric vehicles.”
At the same time, scientists — including a whistleblower from inside The Metals Company’s own exploratory team — have stressed that we know almost nothing about the deep ocean, least of all how a large-scale mining operation could impact everything from regional biodiversity to the potential extinction of undiscovered animals to ocean carbon sequestration. The nodules alone take millions of years to form.
On Monday, the International Seabed Authority kicked off a two-week-long meeting to discuss potentially issuing the first commercial mining permits. It’s already met staunch opposition: The United Kingdom just came out as the latest nation to demand a moratorium on deep-sea mining, joining calls for a total ban issued by France, Germany, New Zealand, and at least 13 other countries. (The U.S. is not a part of the International Seabed Authority because it was one of only four countries that declined to formally ratify the United Nations Convention on the Law of the Sea in 1984, thanks to Republican opposition. China, Norway, and Russia are the major proponents pushing for deep-sea mining to open up).
With this as our backdrop, I spoke to Rytz about the making of Deep Rising and the complexities of the deep-sea mining debate. Our conversation has been edited and condensed for clarity.
Tell me a little bit about how you discovered this story. As the narration points out, deep-sea mining is “out of sight and out of mind” for most people.
I discovered it in 2018 when I was finishing my previous film [Anote’s Ark], and working with the president of Kiribati in the middle of the Pacific. Because of the work I was doing, I had privileged access, since the president was the main character of my film. I started hearing the conversation about deep-sea mining when basically nothing was in the media; it was an absolute unknown story. It really intrigued me. I was like, Wow, this is a very interesting, complex story. I jumped on it and went on the long journey till now.
The U.N.’s International Seabed Authority begins a nearly two-week-long meeting this week that will potentially end with the issuing of the first provisional licenses for deep-sea mining. What has it been like to follow these developments while you’re in the final stages of releasing and promoting this film?
Once the mining code — if the mining code — is ratified, it will be extremely hard to change it. It’s not like in government when you have political football between two parties. Once the regulation is in place, it might take the same amount of time just to make an amendment because you need to get a consensus of all the U.N. members. So it’s a critical time now because they’re actually drafting it and if it passes, the text will define how deep-sea mining will go.
There’s still a chance, actually, to block it or to postpone it. There has been a big wave of countries signing a moratorium and there was very big news yesterday, from the U.K., which is supporting the moratorium. We’ve seen some smaller states sign it; France was a big one, but the U.K. is a significant gain in the movement for a moratorium.
But for me — and this is the story of Deep Rising as well — I’m like, well, okay, sure, let’s say deep-sea mining is stopped by a ban or a moratorium or simply because the mining code doesn’t happen. That doesn’t stop the need for nickel. And that, for me, is the biggest conversation, because if deep-sea mining doesn’t go ahead, it will mean way more pristine ecosystems are torn down in tropical rainforests — mainly in Indonesia, but also New Caledonia, the Philippines, Madagascar, a lot of places. In northern Russia, they’re mining nickel in the tundra and they’re releasing massive amounts of methane.
So for me, it’s not one or the other. Deep-sea mining is better because we’re going to save the rainforest is a fundamentally flawed argument. Because we don’t need nickel in the first place; there are solutions that are not based on finite resources. There’s battery chemistry that is based on iron-phosphate batteries. Green hydrogen is another very good example and a very good debate.
And, you know, we don’t need to buy that many private cars; we need to develop and share resources. When you see the climate bill from President Biden subsidizing every citizen to buy an EV, it’s basically subsidizing removing the pristine ecosystem in Indonesia. I don’t call that a climate plan.
I wanted to ask you about that. The script of Deep Rising can be pretty critical of the energy transition, calling it the “so-called green revolution.” Can you tell me a little about the use of that term, “so-called”?
This is exactly what I mean. You take the narrative of the “green revolution” from the official perspective — the president’s perspective or the industry’s perspective, from President Biden or Elon Musk. Let’s say they have the same narrative: Buy a Tesla and you’re going to save the planet. Because Tesla would not exist without subsidies; every taxpayer in the U.S. has spent massive amounts of money to make it happen. And I’m not against EVs, but it’s important to understand the climate has no boundaries. If you remove the ecosystem in Indonesia, you’re increasing the climate crisis in the U.S., and so on. You’re putting your citizens at risk. Every country is similar.
There’s no reason to go after finite resources like nickel. Again, if there was no solution, it’d maybe be like, “Oh, there’s a trade-off.” But the point is, at a very large, industrial scale, there are solutions to produce energy without extracting finite resources.
In the film, the narration states that “critical metals are not the solution; they are the new oil.” I’m convinced that there could be grave ecological consequences to deep-sea mining, but how do you reconcile that against the grave ecological consequences of the fossil fuels we’re extracting and burning now?
Again, it’s a matter of changing the chemistry of the batteries. If you take the composition of the Earth’s crust, nickel is 0.009%. Iron is 5%. Iron is everywhere. A company like BYD in China, they’ve been very successfully building for like five years now EVs that are as good as Tesla’s with no gram of nickel, no gram of cobalt. Iron and phosphate are widely available. Rivian, in the U.S., they’re also shifting. And that can happen — anytime soon, GM or Ford or Toyota could change their battery chemistry.
Wait — if this is something we have the technology for now, and it’s scaleable, why are mining companies spending all this time and money building deep-sea vacuum cleaners to suck up nodules to power batteries that we don’t even need to be using?
Because there’s a whole supply chain that’s already been built. And when you’re investing billions of dollars to build battery factories, you need to sell enough batteries to recoup your investment. The problem is we made the investment in the wrong direction.
The second problem is political. The EU could ban nickel in the battery and that’d be it. Then Volkswagen and Volvo and BMW and Renault, all the German and French carmakers, would have no choice. I don’t think it’s as easy in the U.S. but in the EU, that’s a move they could do. It’s happening: The U.K. did a moratorium [on deep-sea mining]. France did a total ban. And, of course, some will lose a lot of money, but it’s the right thing to do.
And the Chinese, by the way — most of the domestic market doesn’t use cobalt and nickel. They’re very advanced; the Blade technology from BYD is years ahead. But they’re not exporting that much because of the commercial war, basically.
On your website, you have a manifesto, which states that your aim as a filmmaker is to “ask uncomfortable questions instead of providing reassuring answers.” Can you talk a little about how that philosophy guided your approach to this film in particular?
My background is not in filmmaking; it’s in anthropology. I think because of my upbringing as an intellectual, I can see a system’s complexity. Filmmakers can sometimes cut straight to a conclusion and for me, it’s very challenging because I needed to simplify when making a film. I think I’ve oversimplified already; I see the film and I think “Oh, this is so oversimplified!” even when it’s a very complex film for most of the viewers.
I could have done a film that was just bashing the mining industry, showing how bad they are and how bad capitalists are destroying the planet. The problem with this is, you preach to the choir. The people you actually need to talk to, they will not listen.
Instead, I got invited to speak to the finance sector, the mining sector, a few weeks ago at a big conference in Geneva. Some of the biggest hedge funds and banks — a Swiss bank, a European bank, a Singaporean bank — they were all in the room. They were asking me for advice about if they should have deep-sea mining in their portfolio. We’re talking hundreds of millions of dollars. And I was like, “I can explain to you why you shouldn’t.”
The change is massive when you can tap into the higher side, the financial system, basically. For me, it’s a really interesting goal, because I take this approach so it’s like, “Oh, you’re not just bashing us and saying how bad we are. Let’s set aside our differences and sit down for coffee.”
I wanted to ask about the disagreement within the Pacific Islands communities. On the one hand, you show grassroots resistance to deep-sea mining in Papua New Guinea; on the other, you also show a delegate from Nauru (which sponsors a subsidiary of The Metals Company) pressuring the International Seabed Authority to make a quick decision on commercial licensing. Is the jury still out on deep-sea mining when it comes to regional community support?
There are two forces here. One is that no corporation can apply for a deep-sea mining license. The Metal Company cannot go to Jamaica and say, “I want to mine the deep ocean.” You need to find a country that will sponsor you. So the Metal Company can fly into Nauru, the smallest country in the world, and promise them the moon. Nauru is a very specific story with a long history of extraction with the Commonwealth, with Australia, New Zealand, and Canada. They’ve been mining phosphate since the Second World War. So this is a very specific case.
When it comes to other countries, like Kiribati and a lot of other island nations, they’re kind of under the Chinese now. And there’s a lot of paradox with China because again, the domestic market is very different than the exporting markets. They’re fueling the rest of the world with nickel, so they have six licenses [in the Clarion-Clipperton Zone] and they’re lobbying quite hard now to get deep-sea mining approved. But they own 60% of the nickel capacities globally and the U.S. has 0%. So for the Chinese, they’d still get all this nickel to basically keep the rest of the world dependent on them.
I have to ask about the cinematography, which is absolutely gorgeous. I think a lot of times deep sea animals don’t get the respect of more charismatic environmental icons like polar bears or whales because they look so alien and creepy. But the footage you included really gives this part of the world vibrance, life, and personality.
It came from years and years of digging through hard drives. A lot of the footage comes from scientific expeditions. It was a very long process for me to convince the researchers to give me the license to use their footage, too, because their first reaction was like, “No, it’s scientific material; that specific jellyfish, which is undiscovered, is under embargo.” Which means the scientists haven’t published their paper yet. And I was like, “Guys.”
Is there anything else you’d like our readers to know?
The concept of the common heritage of humankind is very important. It’s outlined in the Law of the Sea, a set of strong rules by the U.N., that the deep sea belongs to humanity. And every citizen of the planet has a shared responsibility to really look at what is happening because it’s the biggest land grab in human history. The mining area is the size of Mongolia. It’s enormous: I mean, imagine if Mongolia, which is an entire country, was mined entirely. It doesn’t make sense. We have a shared responsibility because we know the climate crisis doesn’t have boundaries. Everyone is concerned.

The problem isn’t just affordability, two researchers from Heatmap and MIT’s Electricity Price Hub argue. Bill volatility also creates pain for electricity consumers.
Americans have come to expect shocking electricity bills, especially in the summer months. The latest data from the Electricity Price Hub makes clear: Households in every region of the country are seeing not just record high July bills, but also bills that are sharply higher than even just a few months before.
Some may see these trends and argue that utilities and regulators set rates, but bills are ultimately the result of consumer choices about how much electricity to use. But that narrative misses the mark for a simple reason: How utilities and regulators design rates influence both summer bill swings and how much electricity consumers use. Seasonal rates and other features of electricity pricing can exacerbate summer bill swings and inform customers’ decisions about whether certain electricity uses — even running the air conditioner on an extremely hot day — are worth it.
The scale of this summer’s electricity bill increases is striking. Nationwide, the average household electricity bill was $90 per month, or 71% higher in July than it was in April of this year. Not only are bills up, they are up from a high base. The national average bill in April 2026 was higher than any previous April average in the Electricity Price Hub data, and 37% higher than the national average in April five years ago.
These trends are not just driven by a few states. There are households in every corner of the country experiencing sharp increases in their power bills this summer.
At the state level, average household bills have increased the most in New Jersey (up 163%), Nevada (157%), and Oklahoma (133%), but bills have at least doubled in 11 states and are up 1.5 times in 24 more.
In 19 different states, average household bills from major utilities at least doubled from April to July, adding between $72 and $214 per month to their average customers’ bills. In 12 of those states — including some in the Northeast, Mountain West, South, and Southeast — more than 40% of all households are served by utilities whose average bills have at least doubled this summer.
Greater electricity use is a big part of what’s at play in these trends, but it’s not the whole story. Higher summer rates also contribute, in many cases. Rate design, market conditions, and regulatory processes can all cause electricity prices to change throughout the year.
Some utilities, for instance, have rates that vary seasonally, automatically adjusting in the summer months. Seasonal rates contribute to summer bill increases for eight of the 10 utilities whose average bill increased most from April to July. For three of those utilities, over half of the April-to-July increase was driven by seasonal rates. For another five, seasonal rates play a meaningful role, compounding usage-driven increases. For only two does the increase come back to usage alone.
Taken together, these findings suggest that summer bill shocks are not simply a function of warmer weather. In many cases, they also reflect deliberate choices about how utilities price electricity during the summer months.
Even where higher usage is the primary driver of rising summer bills, the way utilities structure rates influences how much customers can save by using less electricity or shifting when they consume power.
Across the utilities with the largest April-to-July bill increases, there is considerable variation in how they calculate a customer’s monthly bill. All include a mix of fixed monthly fees and charges based on usage, measured in dollars per kilowatt-hour. But the balance between these components differs significantly, with fixed charges contributing from 4% to 23% of average bills over the past 12 months. Some utilities apply the same per kilowatt-hour rate year-round, while others increase rates in the summer. For some, the same rate applies to the total amount of electricity customers use in a month, while others have rates that increase for higher tiers of usage.
That means the design of residential rates also determines how much households actually benefit from using less electricity. Two households may receive similar-sized bills, but depending on how their utilities structure their rates, customers can see very different savings from cutting back.
The three New Jersey utilities in the top 10 illustrate one approach: They all have relatively small fixed customer charges, along with per-kilowatt-hour rates that vary both seasonally and by usage tier. For example, Jersey Central Power & Light’s distribution charge shifts from a single volumetric charge in the winter to a tiered structure in the summer, with usage above 600 kilowatt-hours priced at a higher rate. This structure contributes to sizable seasonal bill swings, but it also creates a strong financial incentive to limit summer usage.
The average household in JCP&L’s service area used more than 1,000 kilowatt-hours in July 2025. Had that household used 15% less electricity, it would have saved roughly $50 that month; a 25% reduction would have saved $82. At current rates, a 25% reduction in usage would cut the average bill by 28%, and every 4 kilowatt-hour reduction in usage over 600 kilowatt-hours saves a dollar.
Nevada Power takes a different approach. Its residential rate consists of a larger fixed customer charge — contributing 14% of total average bills over the last year — and a set of volumetric rates that do not vary by season or usage level. As a result, consumers have less of a financial incentive to reduce consumption. A household would need to reduce usage by roughly 8.4 kilowatt-hours to save a dollar, and cutting electricity use by 25% would reduce the bill by about 23% — meaningfully less than under JCP&L's structure.
While seasonal variability in bills is expected and not on its face problematic, it is important to recognize that unpredictability and month-to-month volatility in power bills can compound energy affordability challenges. And although regulators cannot control the weather, the choices they make about rates influence the agency households have in managing their bills each month.
This then raises the question: Should utilities and regulators consider bill stability and its impact on affordability in setting rates? Staff for the Arizona Corporation Commission, which is currently considering requests from the state’s two investor-owned utilities to raise average household bills by around 15%, recently testified that “affordability and energy burden are not pertinent to ratemaking” — that they are, instead, “societal issues.” But that is exactly the wrong sentiment.
Affordability and bill stability both deserve to be explicit considerations in ratemaking, carefully weighed against other objectives and not dismissed or treated as an afterthought. Doing so may look different in different places and does not require prioritizing bill stability over all else. But where households are struggling to manage unpredictable power bills, regulators should be sensitive to those trends and lend greater weight to measures that boost households’ ability to manage usage and limit bills, should they choose to.
That may mean more effective and targeted energy efficiency and demand response programs and incentives for utilities to promote uptake. In some cases, it may call for better customer education on available rate schedules and ways to manage bills, and ultimately it may require more modern rate design. Whatever the response, stability is part of affordability. Wild bill swings add to the burden of record-high bills — a fact that utilities and regulators cannot afford to ignore.
On Trump’s mineral deals, the gas turbine backlog, and Turkic offshore wind
Current conditions: Tropical Storm Lala could strengthen into a hurricane before hitting Hawaii’s Big Island, becoming the first such storm to make landfall there since 1900 • A glacial outburst at Suicide Basin near Juneau, Alaska, is raising the Mendenhall River • Temperatures surpassed 107 degrees Fahrenheit in Zaragoza, the inland capital of Spain’s Aragon region.

The United States is rapidly approaching a two-decade streak as the world’s No. 1 producer of natural gas. The country held the top spot between 2009 and 2024, the latest year for which the U.S. Energy Information Administration has data. But America pumped record volumes of natural gas last year. And now the federal energy research agency forecasts 2026 will be another record year. Marketed natural gas production — the total volume that actually makes it to market, minus what’s burned off or leaks as waste — is set to reach an average of 122.5 billion cubic feet per day in 2026, up from 2025’s record of 118.5 billion cubic feet per day. The new milestone is the result of expanded drilling in the Permian region that straddles Texas and New Mexico, and in the Haynesville area, between Texas and Louisiana.
When the Trump administration first started buying up equity stakes in mining companies, former officials from the Biden administration told my colleague Matthew Zeitlin they were “jealous” that the Republican White House had the guts to try something novel to compete with China on the metals needed for defense and energy technologies. Now, however, top Democrats are asking federal watchdogs to probe whether the American taxpayer is actually getting good deals. New Mexico Senator Martin Heinrich, the ranking member of the Senate Energy and Natural Resources Committee, and Representative Jared Huffman, the top Democrat on the House Natural Resources Committee, called on the Government Accountability Office to open an investigation into potential conflicts of interest. In a letter sent last week to Acting U.S. Comptroller General Orice Williams Brown and published Thursday on E&E News, the lawmakers accused the White House of violating rules to assess the financial risk of federal purchases. “These equity acquisitions also create potential conflicts of interest for federal agencies because a significant portion of the planned mining operations are located on federal lands,” they wrote. “With the executive branch now holding direct financial equity in these private mining operations, the federal government is required to act simultaneously as a mining investor and land-use regulator, an inherent conflict of interest.”
Mitsubishi’s backlog of orders for large-frame gas turbines is now more than twice its output from last year. In the 2025 fiscal year, the Japanese industrial giant delivered 16 gigawatts of gas turbines and had a backlog of 23 gigawatts. Just halfway through 2026, that backlog has ballooned to 35 gigawatts, executives told investors on the latest quarterly earnings call. The update, announced in Japan last week and covered in English by Utility Dive on Thursday, shows that “demand for large-frame gas turbines remains broadly in line with, or slightly above, the strong level we had anticipated,” Hiroshi Nishio,the chief financial officer of Mitsubishi Heavy Industries.
Power electronics maker Heron Power, meanwhile, unveiled plans for a $100 million factory in Morgan Hill, California. The startup, led by a former Tesla executive, aims to produce next-generation transformers that can patch more solar panels and batteries on the grid and help ease some of the issues that arise from the direct current-based electricity sources. The first factory is designed to churn out 40 gigawatts of Heron Links, the transformer product, per year. “America's grid has to grow faster than it has in decades. We’re seeing new demand from AI and EVs, and at the same time new supply from solar and storage,” Drew Baglino, Heron Power’s chief executive and founder, said in a statement. “The equipment running the grid hasn’t changed in 50 years. Heron Factory One in Morgan Hill is how we fix that. We’re manufacturing the leapfrog technology our grid needs, at scale, in America first.”

Offshore wind is in retreat in the U.S., where, as my colleague Robinson Meyer wrote this week, the Trump administration is paying billions to kill projects that were already dead or dying. The industry’s tide is also ebbing in Japan, where the new right-wing government of Sanae Takaichi is putting a heightened focus on nuclear power. Elsewhere, however, offshore wind is booming. Europe is only expanding its plans. China is steadily dominating the industry. And East Asian countries such as South Korea and Taiwan are expanding their sectors.
Now two of the richest countries in the Turkic world are laying plans for more offshore turbines. Turkey announced plans this week for its first offshore wind tender in the first quarter of 2027, Renewables Now reported. Azerbaijan, meanwhile, this week formally designated a 275-square-mile section of water in the Caspian Sea for offshore wind development, per offshoreWIND.biz. The moves highlight the extent to which the U.S. government stands alone in its view that offshore wind has no role in a modern electricity mix. Turkey, after all, is doubling its domestic production of gas and completing its first nuclear plant. Azerbaijan is famously rich in natural gas and produces a decent amount of hydropower. Yet both countries are still charging ahead on offshore wind.
Deep-sea mining isn’t yet technically legal in international waters. But the Trump administration isn’t waiting, creating the regulatory frameworks for domestic approvals and opening the area around one of America’s Pacific territories to exploration. Japan has been eager to follow suit. Now Washington and Tokyo are planning to meet “centuries’ worth of industrial demand” by establishing what Mining.com called the world’s deepest undersea mine in a bid to take on China’s mineral dominance. The mineral extraction would take place more than 1,000 miles southeast of Tokyo on an uninhabited speck of land called Minamitorishima, where Japanese scientists carried out tests pulling rare earths out of mineral-rich mud.
China is actively building more reactors at home than all other countries combined and singlehandedly restarted the race for novel technologies after hooking the world’s only commercial high-temperature gas-cooled reactors up to the grid in 2023. So far, Beijing’s two state-owned nuclear companies have remained focused on building light water reactors. Just one new high-temperature gas-cooled unit, designed to have more than twice the output of the first version, is currently underway at a facility where the fourth-generation, helium-cooled technology will be paired with third-generation, water-cooled reactors. Now the developer, the China National Nuclear Corporation, has made plans to procure a contract for the reactor for the first time, laying the groundwork for future deals to purchase units specifically designed to reach high temperatures. The “first concrete” for the plant is expected to be poured by the end of 2026, World Nuclear News reported.
Investment in zero-carbon energy and transportation surged this spring, driven by consumer EV and battery buying.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
Ready to be surprised? Clean energy and transportation investment surged in the second quarter of this year, rising to more than $75 billion in total, according to new data released earlier this week.
In fact, this spring was the second biggest quarter for U.S. clean investment in nominal terms since at least 2018, when data started to be kept. More than 5% of overall investment in the United States went into a clean energy or transportation industry.
That’s according to the Clean Investment Monitor, a joint project of the MIT Center for Energy and Environmental Policy Research and the Rhodium Group, a private research firm. The monitor tracks nationwide investment across a number of sectors that make up the new electricity economy, including critical mineral refining, battery manufacturing, solar and wind installation, and electric vehicle and heat pump purchases by consumers (among other variables).
Outside of a promising headline number, the story is a mixed one. Investment in America’s clean manufacturing sector started growing again last quarter after falling for 18 months; it remains about 24% below where it was a year earlier, according to the project. The new growth came overwhelmingly from investment in the EV supply chain — defined as “critical minerals, batteries, vehicle assembly, and charging equipment” — driving a staggering 88% of all clean manufacturing investment. That subsector alone made up more than 9% of all U.S. clean investment.
The more interesting story — and what leaps out from the chart — is that retail activity drove the spring resurgence. High gasoline prices helped here, pushing consumers to buy all-electric and plug-in hybrid vehicles in larger numbers. (Rivian, Tesla, and other automakers started to see an EV rebound last quarter, too, after Republicans ended EV incentives in 2025.) But the real boom came in residential batteries, which surged to an all-time high of $11 billion in quarterly sales. Consumer activity hasn’t made up such a large share of national clean investment since 2023.
This trend wasn’t just happening in the United States. We’ve talked a lot at Heatmap about whether the Strait of Hormuz crisis will drive a clean energy boom. But it's now clear the oil price shock really did encourage global EV adoption. Some 50 countries set new EV sales records in 2026’s second quarter, according to Kelley Blue Book. India, Brazil, and Australia all set record highs. That's a lot of demand destruction.
